F35是单发?之前还以为是像F22那样的双发,惭愧 不过F35可以垂直起降,海航一向双发是为了短距离加推力起飞吧。B号是重了些,但是这个问题已经得到注意了,LM公司也对F35的结构进行了全面优化
The F-35B variant was in danger of missing performance requirements because it weighed too much — reportedly, by 2,200 pounds (1,000 kg) or 8 percent. In response, Lockheed Martin added engine thrust and shed more than a ton by thinning the aircraft's skin; shrinking the weapons bay and vertical tails; rerouting some thrust from the roll-post outlets to the main nozzle; and redesigning the wing-mate joint, portions of the electrical system, and the portion of the aircraft immediately behind the cockpit.
当然,在所有单发战斗机中,F35仍是最重的。
就目前看来,F35还是新出实验品阶段,与F22肯定无法相提并论,不过以后取代F22成为大规模生产战斗机也是可能的,改良余地很大。 |
